Fernando Torres believes Spain have the temperament to go all the way in Germany.

Luis Aragones' side came from a goal down to clinch a 3-1 win over Tunisia on Monday, thanks to three strikes in the final 18 minutes.

The result sees them through to the knockout stages of the World Cup with Saudi Arabia still to come on Friday.

"It has been more difficult than we expected," said Torres, who scored twice in the victory.

"After our 4-0 triumph against Ukraine in our opener, we really thought that everything was done.

"We are slowly gaining confidence in our football. Some days we play well and other days we are made to suffer but the important thing is we now know that if we work as a team, as we did against Tunisia, we can overcome anything."

Liverpool midfielder Xabi Alonso also feels his side can only get better.

"Our patience has been tested," he said. "But this is good for us and gives us optimism for the future. This victory will give a real boost to our morale. It will make us stronger."

His club colleague Luis Garcia was unhappy after he was replaced at half-time by Raul.

The substitution did, however, prove crucial as the replacement struck the equaliser to spark Spain's comeback.

"No-one likes to be substituted and at that moment you feel angry," said Garcia.

"But it's all for the good of the team and as long as we win, that's all that counts."
